What Are QuickCrystal Ads?
If advertisements with captions “Ads by QuickCrystal”, “Ad by QuickCrystal”, “Provided by QuickCrystal”, etc., keep appearing when you browse the Internet, your computer is infected with QuickCrystal adware. Likely you unknowingly agreed to the installation of this adware yourself, when you were installing software from a free download site and didn’t decline extra programs offered. The result: pop-ups and pop-unders, video advertisements and banners that don’t originate from the sites you visit but are caused by something on your computer. The instructions below will help you to get rid of QuickCrystal adware and stop the ads.
